MACHiNE FOR MAKING BARBEDVWSREQ SPECIFICATION forming part of Letters Patent No. 281,120, dated July 10, 1883.

Application filed February 27, 1883. (No model.)

To 0113 whom it may concern:

Be it known that I, JOHN W. NADnLnorrER, of the city of Joliet, in \Villconnty, and State of Illinois, have invented certain new and use ful Improvements in Machines for Making Barbed lVire, the construction and operation of which I will proceed to explain, reference being had to the annexed drawings, in which Figures 1 and 2 are plan views on the top; Fig. 3, a side elevation, looking at Fig. 1 from the upper end; Fig. 4, a side view of the reciprocating racks that rotate the wrappingpinions; Fig. 5, a vertical sectionof the wrapping-pinion containing the strand-wire crossers; Fig. 6, a view on the top of the barbgrasper, and a cross-section of the cutting-off die and the barb-bending posts; Fig. 7 a side view of the barb grasper and feed; Fig. 8, a

' Fig. 13, a plan view on the bottom of the upper die, a, of the barb-grasper; and Fig. 14, a crosssectional view of the eye on the end of one of the fingers, 6 showing the'rcmovable friction-plates e, through which the strandwire passes; Fig. 15, an enlarged side view of the wrapping-pinions, showing the gatherers y, and the manner in which they deliver the prongs of the barb into the notchof the wrappers.

This invention relates to certain improvements in machines for forming the barb of a short piece of wire and placing it on the two strand-wires, all at a single operation, and is of that class of machines that receives the plain wire, both for the strand-wires and for the-wire of which the barbs are to be formed, off of suitable spools located near the machine, and automatically forms and places the barb on the strand-wires, and delivers it finished for fence purposes, and in this instance forms what is known as a double-strand two-pointed barbed wire.

The new features in this invention consist,

, more particularly, in the mechanism for form- Referring to the drawings making a part of this specification, B represents a bed-plate supported on suitable legs, 2. At one side of and attached to said bed-plate B is the main drive-shaft A, having at its outer end the main drive cog-wheel A, 'to which the power is applied by means of pinion D, while its outer end is provided with the bevel-gear J to run the counter-shaft L, from which countershaft the working parts of the machine receive their motion by means of the cams K, K, K and J I P and P are the two barb-wrapping pinions through which the strand-wires W WV enter the machine, as shown in Fig. 1, and between which the barb b is wrapped on said strand wires. Said wrapping-pinions are hollow, and of sufficient diameter within to admit of the crossing of the strand-wires within one of the pinions, as shown in Figs. 5 and 11. A pair .ofiingers, e and 6 (shown particularly in Fig.

5,) enter within the wrapping-pinion P, and are provided at their extreme outer ends with eyes through which the strand-wires W WV pass on their way into the machine. These fingers e and c are pivoted together, on the same pivot, e, to the frame B, just outside of the pinion F, and extend thence downward, in the form of a bell-crank and crotch, over the double cam e and c on the shaft A which double cam gives an opposite motion to the fingers e and 6 as shown in Figs. 5 and 11, alternately, bymeans of which the two strand wires are carried past and crossed oneover the other, back-and forth between the wrappingfpinions, just at the point the barb is to be placed on, as shown, and more particularly hereinafter set forth.

The wire v from which the barb b is formed,

- toothed connection.

enters the machine on a line parallelwith the strand-wires W W, by means of a feed, (shown in Figs. 1, 3, and 10,) and consists of the feedrollers F F, shaft H, and a similar shaft to which is attached the roller F, pinion H, which meshes with a similar lower pinion attached to the shaft of the roller F, forked segment 0 segment-case F loosely attached to shaft H, ratchctwheel Z, firmly attached to shaft H, and cam having the wrist-pin O firmly attached to the drive-shaft A As the drive-shaft A rotates the wrist-pin O engages with thealternate inner sides of the forks of the segment 0 causing it to oscillate on the pivot O, which causes the segment-case F to oscillate in like manner by means of their WVithin the case F is a pawl which engages with the teeth of the ratchet-wheel Z causing said ratchetavhel to rotate partially and intermittently, and with it the shaft to which it attaches, and also the feed-rollers. At each such partial rotation of the feed-rollers a suffieient quantity of wire is fed in to make a barb. I make no claim for this feed, as any feed that will intermittently feed in the barb-wire will answer the purpose as well. The feed feeds thebarb-wire 10 into the machine intermittently as needed, and just long enough at each feed for a barb. After the barb-wire w leaves the feed it passes 011 and is grasped by a jaw or grasper, 0, (shown particularly in Figs. 6 and 7 detached fromthe machine,) and lies in said grasper-j aw and between the cutting-off dies n and n, where it is cut off diagonally, as is shown in Fig. 6, until it is formed into the shape of a staple having a long body, as shown in Fig. 1 at b, and then carried forward by said jaw c and delivered into the strand-wircs,so that each leg or prod of the barb enters between the two strand-wires w, a prod on either side of the cross, as shown in Figs. 1, 2, and 3, after which the wrapper t of the wrapping-pin'ions P and P catch each leg or prod of the barb and wrap it in the form shown in Fig. 2.

The manner in which the barb is formed and fed into the strand-wires is as follows: After the barb-wire w has been fed into the machine and a portion of its end long enoughfor a barb has been grasped by the grasper c, the cutting-off die n,which is fastened into the pendulum-block D", is caused to swing forward by means of its attachment to the arm D which is pivoted at its upper end between the points.

Fig. 1, and is operated by the cam K, Fig. 9, swings forward and cuts off the barb-wire diagonally between the dies 11. and n. The location of said dies a and n is shown more clearly in Figs. 3, 6, and 9. The graspingjaw c is located in the machine, so that its part that grasps the barb stands at the foot and immediately under the pendulum-block D on the arm T, (shown in Figs. 3 and 7,) and between a pair of bending rods or dies,h h,

that are also attached to said pendulum-block D and held firm by the plates n and n (shown in Fig. '3.) The barb-wire passes into and through said grasping-jaw 0 just infront'of these bending-dies h h. The cam K swings the block D forward far enough to cut off the barb, as before stated, and far enoughso that the two bending-dies h, in their movement forward, strike against each leg or prod of the barb and carry them forward far enough to bend its legs or prods straight-forward and at right angles with its body, in the form shown in Figs. 1 and 6 by the dotted lines. Fig. 6 shows more clearly the location of the barb both before and after it is formed, 0 representing the jaw holding the barb, n representing a section of the upper die attached to the endulum-block D" n bein a lan View on P 7 s P the top of the lower die, (shown also in Figs. 3 and 9,) h representing the bending-dies attached to the same pendulum-block, D. The dotted lines show the position of the cuttingoff dies n and the bending-dies h after the pendulum-block has swung forward with the cutting-off die a and the bending-dies h and cut-off'and bent the barb, as shown in said Fig. 6. While this operation of cutting off and bending the barb is being performed the cam-wheel K, which operates the jaw c to move it forward, has permitted said jaw to remain stationary; but said cam K, is soset on the shaft L with relation to cam K that the instant cam K has moved the dies tocut and form the barb cam K has then rotated far enough to move the jaw 0 forward, as shown by the dotted lines in Fig. 7, carrying the barb forward firm in its grasp until it has driven each leg or prod of the barb between the strand-wires immediately over the place where they cross each other, as shown in Figs. 1, 3, 7, and 11, which grasp is not released until the wrappers t t of the wrappingpinions P and P have begun to wrap the prods on the strand-wires, when the jaw 0 opens and returns to perform another like operation. The grasping-jaw c is caused to prolong its grasp on the barb by reason of the upper half of the jaw being attached by the link i to the bent arm t, which has its inner end pivoted to the side of the vibrating arm T with the arm m, while its outer end rides on the shaft L on the cam J (Shown in Figs. 7 and 8.) As the arm T is being carried forward the bent end of the arm 1' will. ride 011 said cam J in such manner that it will continue the grasp of the jaw c on the barb until it has been delivered into the strand-wires, when such grasp will be released on account of the cam J 2 hav-' e and "c and remains there until the barb has been delivered between the wires, when it is 2si,i20 i 7 immediately removed. This finger c is operated by the cranks (F and d by means of the wrist-pin d on the cam 1), attached to the side of cam K, as shown in Fig. 1. Were it not for the finger c being thrust in between the strand-wires, as stated, andas shown in Fig. 11, they could not be crossed and held in that position until the barb is delivered into the strand-wires. Immediately upon the barb being delivered into the strandwires, as aforesaid, its points or pro'ds must be wrapped on the strand-wires to hold it on and prevent the strand wires from separatin This is accomplished by means of the wrappers t t on the wrapping-pinions P andP. The construction of the wrapping-pinions is shown in Figs. 4 and 5, and consists of a hollow shaft, having integral cogs around its central circumference, and rotating in the boxes D and D by means of the segmental racks R and R. (Shown in Fig. 4.) The motion of the racks R and R 'is reciprocating in opposite directions from each other, so as to give a corresponding motion to the wrapping-pini'ons-P and P, and is derived from the eccentric cam K on the shaft L by means of the connecting-rods a a a and cranks aa a? on the rocking shaft B, as shown in Figs. 3 and i.

The part of the wrapping-pinionsthat wrap the barb upon the strand-wires consists of the wrappers t t (shown in Fig. 5) on the outer end of an extension of the pinion proper. When the barb has been delivered into the strand-wires,'where they are crossed, and in i the position shown in Figs. 5 and 11, a forward rotation of the wrapping-pinions causes the wrappers t t on each pinion to rotate against the prods of the barb, carrying them around in opposite directions and wrapping them on the strand-wires until they are in the form and position shown in Fig. 2, whenthe wrapping-pinions reverse their motion by means of the return of the racks R and R to their 0rigi nal position, ready to perform another like operation. Should the prods of the barbs spread apart after being delivered into the strandwires, they are gathered, up by the gatherers y y, the inclinedfaces of. which bend them back to aline at right angles with the strandwires. The instant the barb is thus formed the strand-wires are drawn on through the machine far enough so the next succeeding barb can be placed .on in like manner as the preceding one. This is accomplishedbymeans of the take-up shown in Fig. 2. This take-up consists of a pair ofspringdogs, s s", pivoted to the top of the sliding plate S, which reciprocates back and forth by means of the vibrat tion, is not further illustrated or described.

The strand -wires pass between a pair of plates, To", which serve to retain 'one'strandwire over the other and prevent their twisting until after they leave said plates, to prevent the dogs 8 s? from injuring the prods 0f the barbs as they slide along on either side of the strands back and forth to grasp them and draw them through, as stated. \Vhen the barb b is driven in between the two strand wires, it might drive its points against the strand-wires, and thus press them out of line between the wrapping-pinions P P. In order to prevent this, a post, 0, (shown in Figs. 1 and 3,) stands near thestrand-wires, on the opposite side from the side the barb is fed in, and so that when the barb is driven in its prods will stride the said post a, the said post forming a back against which the strand-wires rest to hold them in position while the barb is being so placed in them.

In Fig. 12 the lower die, T", of the barbgrasper or jaw c is shown as being adjustable up or down by means of a set-screw, T, at its lower end, so that when the upper end of said die wears it can be setup to grasp the barb firmly. The upper die-plate, c, of said jaw c is made so it is removable, and is held in place by a screw passing through it, as shown, and having a tail-piece to. extend into the jaw c, as shown in Fig. 13, so it will not movelatorally, and is removable, so when worn-it can be replaced by a new one. The eyes in the ends of the fingers e and 0 through which the strand-wires w w pass, are provided with removable frictionplates e, as shown in Fig. 14, and held in position by the pin 6'', passing through the end of the finger and through a groove in the side of the said friction-plates. These friction-plates are removable, so they maybe replaced by new ones'when worn out.

In order to regulate the grasp of the barbgrasper on the barb, the arm 23, Fig. 12, is pivoted to the side of arm 2', at its lower end, on an eccentric sleeve, i on the wrist-pin i, which passes through it. eccentric sleeve i it is obvious the jaw a will grasp the barb more or less firmly, as desired.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:
